Used in my camper bathroom
“I am very happy with this purchase. It stays flexible and adheres perfectly. The product was as good as described and worked very well. I will purchase again.”

Exactly the caulk I wanted. Still holding as good as the day it was applied.
Great caulk for the price. I was a professional painter for several decades. This product performed as expected. Cleaned mildewed wood with pressure. Then used clorox/soap solution. Days later I sanded and primed the well prepared doors. Allowed several separate coats of primer to fully dry over a couple of days, then applied as much caulk as needed to fill cracks the carpenter could not. The caulk has held up on two crawl space doors, in very damp areas, for several years. If you use this caulk on bare wood instead of primed wood, it will not perform as well.

Great for camper repair
Works great and matches color to repair various areas on a camper. Flex keeps areas sealed.

as good as grout
I have dark ceramic tiles and this blends into the seams and works as good as grout and faster. Use painter's tape on both sides of seam for easier clean up.

Not cheap, but worth it.
This product maintains a seal over a wide range of temperatures without cracking or losing adhesion. It is just like a standard latex caulk in application, and can be cleaned up with water, but durability is much better.
